What is a breast cyst and how is it formed?

Breast cyst is a benign breast lesion characterized by cystic fluid accumulation, which is mostly caused by normal physiological changes or hormonal fluctuations in the body.

A breast cyst can be simply understood as a small "blister" in the breast tissue. It is mainly caused by the expansion of the glands in the breast lobules after being stimulated by hormones, forming a cystic cavity filled with fluid. Fluctuations in estrogen levels, disorders in breast alveolar secretion, and drainage disorders in the breast ducts may all be important causes of cyst formation.

Cysts vary in size, ranging from a few millimeters to several centimeters in diameter. Small cysts sometimes have no obvious symptoms, while large cysts may cause breast pain and discomfort. Some women find that cysts are more obvious before and after the menstrual cycle. This is due to the "influence" of changes in hormone levels on the breast.

Maintaining a regular lifestyle and a healthy diet can reduce the discomfort caused by breast cysts to a certain extent. If the cyst is large or accompanied by obvious symptoms, it is recommended to seek medical attention as soon as possible. Professional doctors can use ultrasound or puncture to make a clear diagnosis and take appropriate treatment measures.
